STRAINER EOR GASOLINE DELIVERY NOZZLES William H: Rice and 'H'ancel' M;Lyon, Atlanta, Ga. Application August/20, 1934, Serial'N0..740,675 5Claims. (01. 210'-164)' This invention relates tornozzles fordelivering.

gasoline from measuring pumps andrelates especially to the means for.coupling the nozzle to the delivery hose. The object of the invention isto provide a novel and .efiicient coupling whereby a strainer will besecurely held within the coupling betweenthe hose and the nozzle so thatthe gasoline delivered through the nozzle will be thoroughly cleaned andthe coupling parts may be easily separated when it is desired to removeany possible accumulation. The invention is illustrated in theaccompanying drawing and consists in certain novel features which wiilbe hereinafterv first fully described and then more particularly definedin the appended claims.

In the drawing:

Figure 1 is a longitudinal section through a coupling embodying thepresent invention.

Figure 2 is a section through the strainer removed from the coupling onthe line 2-2 of Figure 1.

Figure 3 is a perspective view of the strainer and the supporting ringseparated but in their proper relative positions.

Figure 4 is an enlarged detail section on the line 4-4 of Figure 3.

In the drawing,- the reference numeral l indicates a coupling sleevewhich is internally threaded at one end or otherwise constructed to beattached to the end of the hose or pipe leading from the measuring pump.This coupling sleeve is exteriorly enlarged at the end remote from thedelivery pipe or hose, as shown at 2, and the bore of the sleeve istapered or beveled, as shown at 3, whereby the liquid flowing throughthe sleeve will be confined between the wall of the sleeve and the sideof the strai er 4 and will be unable to escape except through thestrainer so that any foreign matter which may be in the gasoline will bepositively caught and retained in the sleeve. The enlarged portion orflange 2 is externally threaded, as clearly shown in Figure l, to beengaged in the coupling head 5 of a nipple 6 which is threaded orotherwise fitted into the end of the delivery nozzle. The formation ofthe coupling head presents an internal annular shoulder 1 upon which awasher 8 of fiber or other material which will form a tight packing, isplaced.

The strainer is of tapered or conical formation, as clearly shown inFigures 2 and 3, and consists of two similar sections which have theirside edges crimped together, as shown at 9, and held in the crimpedengagement by a metal strip I which is doubled thereover, as clearlyshown in Figure 4. The end of the strainer is also formed by compressingthe ends of the two sec-- tions so that they present a flatedge to theinflowing gasoline and these edges are held together by a clip H ofmetal compressed over the edges, as will be understood and as clearlyshown. The side strips IE-are extended beyond the basal or open end ofthe strainer and thereby present terminal tongues which are adapted topassthrough diametrically opposite openings I) in the 10 supporting ringl3 and then doubled upon themselves so as to engage the inner surface ofthe ring, as clearly shown in Figure 1. The basal end of the strainerencircles the ring I3 and extends preferably to the annular flange M onthe ring. The flange l4 rests upon or against the washer I and a secondwasher or gasket 15 of fiber or rubber rests upon the flange I4, asclearly shown in Figures 1 and 2. When. the parts of the strainer andthe supporting ring have been assembled and connected, as shown anddescribed, they are disposed within the coupling head against the washeror packing 8 and the coupling sleeve I is then engaged in the couplinghead and turned home against the washer I5 so that the two washers andthe flange M will be firmly clamped between the end of the couplingsleeve and the annular shoulder within the coupling head.

This coupling is very simple and easily manipulated and, when the partsare properly assem- F bled, the strainer will be very firmly held inplace and will be presented to the oncoming stream of gasoline so thatthe gasoline will be forced to pass through the strainer and bethoroughly cleansed of all minute impurities, it being noted that thestrainer is formed of very fine mesh wire. Whenever renewal of thestrainer is necessary the coupling sleeve may be very readily withdrawnfrom the coupling head so that the strainer and its supporting ring maybe easily lifted therefrom. The terminal tongues of thestrainer-clamping strips may then be readily straightened so as to bewithdrawn through the openings in the supporting ring and its flange topermit removal of the broken strainer and the substitution of a newstrainer. The supporting ring will fit closely within the open end ofthe strainer and the washer l5 will fit closely around the end of thestrainer so that leakage of the gasoline around the end of the strainerinstead of passing through it will be avoided.

Having thus described the invention, what is claimed as new is:

1. A device for the purpose set forth comprising a coupling sleevehaving its bore reduced in diameter at one end and being provided atsaid end with an annular enlargement, a coupling head engaged around theenlargement of the coupling sleeve and having an internal shoulderpresented to the end of the sleeve, washers interposed between the endof the sleeve and said shoulder, a supporting ring having an annularflange fitted between the washers and provided with diametricallyopposite openings, a tapered strainer consisting of longitudinalsections having their edges crimped together and their ends flattened, aclip compressed over the flattened ends of the strainer sections,securing strips clamped upon the crimped side edges of the strainersections and extending beyond the larger end of the strainer, theextended ends of said strips passing through the openings in thesupporting ring and extending inwardly to bear against the inner side ofthe ring and the washer resting upon the flange of said ring fittingclosely around the end of the strainer, said-washer, theannular flangeon the supporting ring and the washer bearing against the shoulder ofthe coupling head being clamped by and between said shoulder and the endof the coupling sleeve.

2. A device for the purpose set forth comprising a coupling sleeve, acoupling head engaged around an end of the sleeve, a strainer, asupporting ring engaging one end of the strainer and provided withspaced openings, and holding strips on the sides of the strainerprovided with terminal tongues extending through the openings in thering and against the adjacent face of said ring.

3. A strainer comprising a supporting ring having oppositely disposedopenings therein and provided wtih a base flange, a tapered strainerhaving its large end fitting over the supporting ring and resting onsaid flange, and securing elements carried by the strainer and engagingthe openings in the ring. l l

4. A device of the class described comprising a. tapered supporting ringhaving openings therein and provided with a base flange, acorrespondingly tapered strainer fitting over the tapered supportingring and formed of mating sections, securing elements uniting the matingedges of the rainer sections and having their lower ends projectingbelow the large end of the strainer and seating in the openings in thering, and a. securing clip engaging the strainer sections at the upperends thereof and interposed between the securing elements.

5. A device of the ly disposed openings formed therein and provided witha'laterally extending base flange, an upbeing formed of mating sectionshaving their meeting longitudinal edges overlapped, and securingelements engaging the overlapped edges of the strainer and having theirlower ends projecting below the large end of the strainer and extendedthrough the openings in the ring and against the inner face of saidring.
